Automobile network to communicate with multiple smart devices

ABSTRACT

Embodiments are directed towards establishing a network between mobile devices, an automobile head unit, and a plurality of automobile accessories. A user utilizes a user interface on a mobile device to send an accessory access request to the head unit. The head unit receives the request and determines if the mobile device is authentic. If authentic, the head unit determines if the mobile device has the proper permissions to perform the requested access of the accessory. If permitted, the head unit generates and sends control commands to the accessory or obtains the requested accessory data and provides it to the mobile device.

BACKGROUND Technical Field

The present disclosure relates generally to an automobile head unit, and more particularly, but not exclusively, to providing a network between the head unit, user mobile devices, and accessories of the automobile.

Description of the Related Art

Automobiles are becoming more and more user friendly and interactive. Many new cars are now manufactured with a user interface, called a head unit, which a user can use to control various aspects of the automobile. For example, the user can use the head unit to change radio stations, change the temperature of the automobile cabin, access maps and global positioning systems, and even access the internet. Advancements in short range mobile communications have expanded the experience of the head unit to the user's mobile phone or tablet. Now, users can access music on their smart phone and have it played through the automobile's sound system. But typically only one user at a time can perform these actions, and the types of actions that the user can perform are relatively limited. It is with respect to these and other considerations that the embodiments described herein have been made.

BRIEF SUMMARY

Briefly stated, embodiments are directed towards establishing a network between a plurality of mobile devices, an automobile head unit, and a plurality of automobile accessories. At some point after establishing a connection with a mobile device, the head unit receives a request from the mobile device to access or control a selected accessory in the automobile. The head unit authenticates the mobile device and determines if the mobile device is permitted to interact with the head unit. If the mobile device is authentic, the head unit determines one or more permissions of the user mobile device. These permissions include one or more operations that the user mobile device is authorized to perform with the selected accessory. Based on the permission of the mobile device, the head unit sends control commands to the selected accessory or obtains the requested accessory data and provides it to the mobile device.

Embodiments described herein provide an enhanced network to enable a plurality of mobile devices to interact with and access a plurality of accessories in an automobile without having to directly interact with the accessories. This network also supports various levels of authentication and permission to prohibit or limit some devices from accessing certain accessories, while providing full access to other devices. These permissions can reduce distractions to the driver while also enhancing the automobile user experience for other people in the automobile.

In various embodiments, the mobile device communication network 120 and the accessory communication network 106 are separate communication networks. It should be understood that in various embodiments, the mobile devices 114-116 cannot connect to and communicate directly with the accessories 108-110. The head unit 104 acts as a gateway between the mobile devices 114-116 and the accessories 108-110 to provide authentication and authorization for permitting or restricting the control of accessories 108-110 and the transfer of accessory data, as described herein.

FIGS. 2A-2B show use case examples of an automobile system. The system includes an automobile 102, a head unit 104, and a plurality of different accessories. The illustrated accessories are examples of the accessories 108-110 in FIG. 1. The accessories include body accessories 208 a-208 d, infotainment accessories 206 a-206 f, and wireless accessories 210.

The body accessories 208 a-208 d are accessories that communicate with the head unit 104 via an automotive body communication network 218. The automotive body communication network 218 may be a controller area network bus that physical connects the body accessories 208 a-208 d to the head unit 104. Examples of body accessories 208 a-208 d include, but are not limited to, air conditioner 208 a, adjustable mirror 208 b, adjustable seat 208 c, and sun roof 208 d.

The infotainment accessories 206 a-206 f are accessories that are embedded in the head unit 104, such as software programs and functions, and communicate with the head unit 104 via infotainment network 216. The infotainment network 216 may be one or more application program interfaces that enable the head unit 104 to communicate with the various infotainment accessories 206 a-206 f.

The wireless accessories 210 include other accessories that communicate with the head unit 104 via a wireless network 220, such as Bluetooth Low Energy or other short range wireless protocol. Although the wireless accessory 210 is illustrated in a back seat of the automobile 102, embodiments are not so limited, and the wireless accessory 210 can be positioned in other locations of the car and may provide control of other accessories.

In various embodiments, the automotive body communication network 218, the infotainment network 216, and the wireless network 220 for communicating with wireless accessory 210 are part of the accessory communication network 106 of FIG. 1.

The mobile devices 114-116 provide requests to the head unit 104 to access or control one or more of the body accessories 208 a-208 d, the infotainment accessories 206 a-206 f, the wireless accessories 210, or some combination thereof. In some embodiments, the mobile devices 114-116 can receive accessory data without sending a request to the head unit 104. In such an embodiment, the head unit 104 may obtain accessory data, which is broadcast from the accessory or requested from the accessory by the head unit, and broadcasted or transmitted via wireless network 220. The mobile devices 114-116 can listen for this broadcasted data from the head unit 104.

FIG. 2B illustrates one example of the head unit 104 and an example of the wireless accessory 210 inside the automobile 102. Although the head unit 104 and the wireless accessory 210 are illustrated as being part of the dashboard of the automobile 102, embodiments are not so limited. In this example, the accessory 210 provides an interface for interacting with other accessories. So, instead of using one of mobile devices 114-116, a user can interact with the wireless accessory 210 to control or access the accessories 208 a-208 d or 206 a-206 f.

The user activates one or more buttons, scroll wheels, or other interfaces on the wireless accessory 210. In response, the wireless accessory 210 sends a corresponding request to the head unit 104 to access or control one or more accessories. The head unit 104 generates the necessary commands to obtain information from the accessory or to control the accessory, as described herein. The head unit 104 returns obtained accessory data to the wireless accessory 210, some other accessory, or a mobile device 114-116.

The operation of certain aspects of the disclosure will now be described with respect to FIGS. 3 and 4. In at least one of various embodiments, processes 300 and 400 described in conjunction with FIGS. 3 and 4, respectively, may be implemented by or executed on one or more computing devices, such as the head unit 104 of the automobile 102.

FIG. 3 illustrates a logical flow diagram generally showing one embodiment of an overview process for receiving a request from a user mobile device at a head unit and executing the request in accordance with embodiments described herein. Process 300 begins, after a start block, at block 302, where one or more user mobile devices are connected to the head unit. The mobile devices may connect to the head unit via one or more networking communication technologies, such as Bluetooth, Bluetooth Low Energy, Wi-Fi, or other short range communication technologies.

Process 300 proceeds to block 304, where a head unit in an automobile receives a request from a mobile device to access an accessory in the automobile. In various embodiments, the mobile device has an application executing on the mobile device. The application provides a user interface for the user to interact with one or more accessories in the automobile via the head unit of the automobile. The user can utilize the user interface to select an accessory to obtain accessory data or to provide commands to an accessory to control the accessory. In one non-limiting example, the user can select the speedometer accessory in the user interface to view the current speed of the automobile. In another example, the user can manipulate temperature controls in the user interface for an environmental control accessory to adjust the cabin temperature. In response to the interactions with the user interface, the mobile phone generates the request, and sends it to the head unit.

Process 300 continues at decision block 306, where a determination is made whether the mobile device is authentic. When the mobile device connects with the head unit at block 302, the head unit and the mobile device may exchange keys, tokens, or other information that is used by the head unit to authenticate the mobile device. The mobile device includes this authentication information with the request. The head unit compares this information with the corresponding authentication information it has stored for the mobile device. It should be understood that other authentication techniques may also be employed to confirm or deny the authenticity of the mobile device.

If the mobile device is authentic, then process 300 flows to decision block 308; otherwise, process 300 terminates or returns to a calling process to perform other actions. In some embodiments, where the mobile device is not authentic, the head unit can send a message to the mobile device indicating that the device has not been authenticated. In other embodiments, the head unit may disregard the request and not notify the mobile device of the unauthentic determination.

If the mobile device is authentic, then process 300 flows from decision block 306 to decision block 308. At decision block 308, a determination is made whether the requested access of the accessory is permitted. In various embodiments, each of a plurality of mobile devices that is connected to, or otherwise registered with, the head unit has various permissions regarding the control and accessibility of each of a plurality of accessories. These permissions may be set by a master mobile device or administrator when the mobile device connects to the head unit or at some other time.

For example, a mother's tablet computer may be a master mobile device with total access and control over the accessories and the permissions of other mobile devices. The mother's daughter's smartphone may only have partial access to a portion, but not all, of the accessories, such as read access of a map function of the navigation accessory and control access to change the radio station. This type of permission restriction allows the master mobile device or administrator to control what the other mobile devices can do. For example, it may be unwise to give the daughter's smartphone permission to turn on the seat warmer for the driver or move the driver's window up and down. But at the same time, allowing the daughter to change the radio channel or even the environmental controls can provide safer driving conditions since the driver does not have to take their eyes off the road or adjust their concentration to change the radio station.

In various embodiments, the head unit stores each mobile device's permissions in a database, which may be local or remote to the head unit. The head unit queries the database for the mobile device, the accessory, and the requested action to determine if the mobile device has the proper permissions. If the requested access is permitted for the mobile device, then process 300 flows to block 310; otherwise, process 300 terminates or returns to a calling process to perform other actions. In some embodiments, where the access is not permitted for that particular mobile device, the head unit can send a message to the mobile device indicating that the device does not have the appropriate permissions to execute the request.

At block 310, the head unit executes the request based on the access permissions of the mobile device, which is described in more detail below in conjunction with process 400 in FIG. 4.

After block 310, process 300 terminates or returns to a calling process to perform other actions.

Although FIG. 3 describes a mobile device sending a request to the head unit, embodiments are not so limited. In other embodiments, the head unit may broadcast or periodically send out accessory data or information, which the mobile device can receive and display to the user. In at least one such embodiment, the data may be encrypted such that only authentic and permitted mobile devices are capable of decrypting and accessing the accessory data. In yet other embodiments, an accessory, such as wireless accessory 210, may send the request to the head unit. In this way, the requesting accessory, rather than a mobile device, can access or control another accessory.

FIG. 4 illustrates a logical flow diagram generally showing one embodiment of a process for executing a request in accordance with embodiments described herein. As described above, a request to access or otherwise control an accessory is received at the head unit from a mobile device.

Process 400 begins, after a start block, at decision block 402, where a determination is made whether the received request at block 304 in FIG. 3 is to send a message to another mobile device. This message may be a short text-based message or image-based message. For example, assume the user of the mobile device wants to tell someone else in the car to close his or her window. The user could do this by sending a request to the head unit to forward such a message to the mobile device of the other person. Embodiments, however, are not so limited. In another example, the user wants to tell a friend where they are currently located. In this case, the user can send a request to the head unit to obtain the automobile's current position from the navigation accessory and send it to the friend's mobile device. If the request is to message another mobile device, then process 400 flows to block 404; otherwise, process 400 flows to decision block 408.

At block 404, the head unit generates a message based on the request. In some embodiments, the head unit repackages the request into a different format or transmission protocol, or performs some other modification, necessary to send the requested message to the other mobile device. In other embodiments, the head unit performs other actions to obtain information for inclusion in the generated message. For example, the request may be to inform the other device of the current location of the automobile. In this example, the head unit obtains the GPS coordinates of the automobile from the navigation accessory and generates a message with the obtained information.

Process 400 proceeds to block 406, where the message is sent to the other mobile device. In various embodiments, the message is sent to the other mobile device via Bluetooth Low Energy protocols, or some other localized communication networking standard. In other embodiments, the message is sent to the other mobile device over a more robust communication network, such as a cellular network. For example, in some embodiments, the mobile device, such as a tablet, may not have access to a cellular network, but the head unit does. The head unit can receive the message from the tablet, generate an SMS message at block 404 and send the SMS message to the other mobile device via the head unit's cellular network access. In this way, users inside the automobile can communicate with others that are not in the automobile.

After block 406, process 400 terminates or returns to a calling process to perform other actions. In some embodiments, the request received from the mobile device may include multiple requests or actions, and process 400 may loop, not illustrated, to decision block 402 to further process the request.

If, at decision block 402, the request is not to message another mobile device, then process 400 flows from decision block 402 to decision block 408. At decision block 408, a determination is made whether the request is to control an accessory in the automobile. The request may include a generic command and an identifier for the accessory to apply that command. For example, the request may indicate the environmental controls accessory and an increase command. In another example, the request may indicate the dome light accessory and an “on” or toggle command. In various embodiments, it may be necessary for the head unit and the mobile device to coordinate or synchronize the accessories and their controllable features. This synchronization may occur when the mobile device connects with the head unit, when new accessories are added or modified, or at other times. This coordination allows the mobile device to send requests that can be understood by the head unit.

If the request is to control an accessory, then process 400 flows to block 410; otherwise, process 400 flows to decision block 414.

At block 410, the head unit generates a command to send to the accessory. The head unit can utilize a lookup table or other database to generate one or more commands to control the accessory based on the received request. In various embodiments, the command is generated specifically for the accessory based on the type of accessory and the communication network utilized to communicate with that accessory. The command includes an identifier of the accessory and an instruction to control the accessory. The head unit generates the command to be in a format, protocol, or other electronic signal that is recognized by the accessory, such that the accessory can perform an action in accordance with the requested control. For example, the request may be to move the passenger's window down. The head unit generates a command that identifies the passenger power window accessory and can be put on the automotive body communication network such that the power window accessory receives the command and activates a motor to move the window. It should be understood that different accessories on different communication networks utilize different commands.

Process 400 proceeds to block 412, where the head unit provides the command to the accessory. The communication network utilized to send the command to the accessory may be dependent on the type of accessory or the connection between the accessory and the head unit. For example, if the command is to move a window up or down, the head unit can utilize an automotive body communication network, such as a controller area network within the automobile. As another example, the command is to control the navigation accessory, such as to enter a destination. In this case, the head unit can utilize an application program interface or other software-related tool to provide the destination provided by the mobile device to the navigation accessory. In yet another embodiment, Bluetooth Low Energy may be utilized to send commands to a wireless accessory, such as a wireless heads-up display accessory.

After block 412, process 400 terminates or returns to a calling process to perform other actions. In some embodiments, the request received from the mobile device may include multiple requests or actions, and process 400 may loop, not illustrated, to decision block 402 to further process the request.

If, at decision block 408, the request is not to control an accessory, then process 400 flows from decision block 408 to decision block 414. At decision block 414, a determination is made whether the request is to obtain accessory data. In some embodiments, the request may identify an accessory, the type of data to be obtained, or an instruction to send to the accessory to cause the accessory to return data. If the request is to obtain accessory data, then process 400 flows to decision block 418; otherwise, process 400 flows to block 416 to perform other actions.

At block 416, the head unit performs other actions, which may include sending a notification to the mobile device that the head unit is unable to process the request, updating a user profile, changing mobile device permissions or authentication status, etc. After block 416, process 400 terminates or returns to a calling process to perform other actions.

If, at decision block 414, the request is to obtain accessory data, then process 400 flows from decision block 414 to decision block 418. At decision block 418, a determination is made whether the requested accessory data is currently cached by the head unit. In some embodiments, some accessories may periodically broadcast or send information to the head unit without the mobile device or the head unit requesting the information. The accessories can send this information at regular time intervals or when the information is updated or changed. The head unit caches this information until it is updated, changed, or for a predetermined amount of time.

In other embodiments, the head unit may obtain and cache accessory information without being requested by the mobile device. The head unit may utilize various prediction algorithms to pre-fetch and cache accessory data. For example, the head unit may obtain the current cabin temperature of the automobile if the user of the mobile device frequently requests the temperature.

If the data is cached at the head unit, then process 400 flows to block 426; otherwise, process 400 flows to block 420.

At block 420, the head unit generates another request to be sent to the accessory requesting the data. Block 420 may employ embodiments similar to those described in conjunction with block 410, but the generated request is a query instruction sent to the accessory to obtain information from the accessory.

Process 400 proceeds to block 422, where the other request is provided to the accessory. Block 422 may employ embodiments similar to those described in conjunction with block 412, but where the other request is to obtain information from the accessory, rather than control some aspect of the accessory. For example, the head unit may provide the other request to the accessory via the automotive body communication network, an application program interface, Bluetooth Low Energy, or some other communication network utilized to send communications between the head unit and the accessory.

Process 400 continues at block 424, where the head unit receives the requested data from the accessory. In some embodiments, the head unit stores or caches the requested data for a predetermined amount of time.

After the head unit obtains the data from the accessory at block 424, or if the head unit currently has the data cached in its memory, then process 400 proceeds to block 426. At block 426, the head unit provides the requested data to the mobile device via the mobile device communication network. In various embodiments, the head unit repackages the request into a different format or transmission protocol, or performs some other modification, necessary to send the requested data to the mobile device.

As described elsewhere herein, the head unit may broadcast or periodically transmit accessory data without receiving a request from a mobile device. In some embodiments, the data is broadcast when it changes or at predetermined time periods. Broadcasting of accessory data enables mobile devices to receive data updates or changes without having to actively send requests to the head unit, which can be received by the mobile device.

After block 426, process 400 terminates or returns to a calling process to perform other actions. In some embodiments, the request received from the mobile device may include multiple requests or actions, and process 400 may loop, not illustrated, to decision block 402 to further process the request.

As mentioned above, an accessory may send the request to the head unit rather than the mobile device. In such embodiments, processes 300 and 400 are performed but with the requesting device being an accessory rather than the mobile device. Similarly, the head unit provides requested accessory data to the requesting accessory rather than the mobile device.

It should be understood that the embodiments described in the various flowcharts may be executed in parallel, in series, or in a combination thereof, unless the context clearly dictates otherwise. Accordingly, one or more blocks or combinations of blocks in the various flowcharts may be performed concurrently with other blocks or combinations of blocks. Additionally, one or more blocks or combinations of blocks may be performed in a sequence that varies from the sequence illustrated in the flowcharts.
